[0002] In automotive steering system design, the tie rod is a key component connecting the steering gear and the steering knuckle. Its function is to transmit torque from the steering gear to the steering knuckle, which then drives the tires to rotate, thus achieving vehicle steering. Therefore, the tie rod plays a crucial role in the entire steering system. Figure 4 This is a schematic diagram of a current steering system. This system uses a steering tie rod in conjunction with a recirculating ball steering gear, and is widely used in off-road vehicles, especially those known for their deep off-road capabilities. Considering the target customers of these vehicles, who frequently modify their vehicles, the current steering tie rod is a single-piece structure with a limited adjustable length, typically 10-30mm. This adjustment range only addresses the overall toe-in adjustment needs of the vehicle and does not consider customer modification requirements, particularly those requiring wider track widths. Therefore, modification space is limited, and modifications are difficult and costly. Summary of the Invention

Detailed Implementation

[0012] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort should fall within the scope of protection of this utility model.

[0013] A steering tie rod system employing a split-type tie rod structure includes a steering straight tie rod 1 and a steering lateral tie rod 2. The right end of the steering straight tie rod 1 is connected to a right steering knuckle 3, and the left end of the steering straight tie rod 1 is connected to a steering gear 16. The two ends of the steering lateral tie rod 2 are connected to the right steering knuckle 3 and the left steering knuckle 4, respectively.

[0014] Both the steering tie rod 2 and the steering straight tie rod 1 include a left support rod 5, a right support rod 6, and an adjusting rod 7. The inner end face of the left support rod 5 and the inner end face of the right support rod 6 are respectively provided with a left internal thread hole and a right internal thread hole. The left internal thread hole and the right internal thread hole have opposite directions of rotation. The outer surfaces of the left and right sides of the adjusting rod 7 are respectively provided with a left external thread 8 that mates with the left internal thread and a right external thread 9 that mates with the right internal thread. The left and right sides of the adjusting rod 7 are respectively inserted into the left internal thread hole of the left support rod 5 and the right internal thread hole of the right support rod 6. A left locking nut 10 and a right locking nut 11 are respectively threaded onto the left external thread 8 and the right external thread 9 of the adjusting rod 7.

[0015] This invention, by setting a left support rod 5, a right support rod 6, and an adjusting rod 7, allows for convenient adjustment of the lengths of the steering tie rod 2 and the steering straight tie rod 1. Moreover, the adjustable lengths are greater than those in the prior art for steering tie rods 2 and 1. Adjustment is achieved simply by rotating the adjusting rod 7. When rotating the adjusting rod 7, because the inner end faces of the left support rod 5 and the right support rod 6 are respectively provided with left and right internal threaded holes with opposite rotation directions, the left support rod 5 and the right support rod 6 will move inward or outward simultaneously. When they move inward simultaneously, the lengths of the steering tie rod 2 and the steering straight tie rod 1 will shorten; when they move outward simultaneously, the lengths of the steering tie rod 2 and the steering straight tie rod 1 will lengthen.
